Weird and surprisingly good route up the backside of the Diesel Driver formation. Tunnel/ scramble up underneath both chockstones (or start on the left of the second) and work your way up and right on steep cracks. Routefinding is kinda tricky but gear is good. End on the upper anchors for Diesel Driver and rap per that route.
The big tunnel with the chockstone when rounding the corner from Blackline to DD. Goes up the left side of the chimney.
Gear to 2.5" (one fixed piton) Please be careful as there is a lot of loose stuff all over this route, particularly at the base.
